li/IACVHINE FOR ORNAMENTINGMWOOD.

SPECIFICATION forming part of Letters Patent No. 242,933, dated June 14, 1881.

` Application tiled May 2,1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN P. JAMISON, of Cambridgeport, in the county ot' Middlesex I and State ofMassachusetts, have invented certain new and useful Improvements in Machines for Ornamenting Wood and otherOompressible Materials, of which the following, taken in connection with the accompanying drawings,

is a specification. 1 i

My invention relates to a machine for forming sunken designs in wood and other compressible material by direct pressure of a ilat die or a design in relief formed upon a hat surface; and it consists in a novel `construction and arrangement of the bedsurface, upon which the material rests while being acted upon by the die, and in the manner ot' applying the size to the die, all ot' which will be readily understood by reference to the descri ption of the drawings, and the claims to be hereinafter given.

'Figure l of the drawings is a front elevation of a machine embodying my invention. Fig. 2 is a side elevation with the treadle broken away. F ig. 3 is a partial vertical section on line :v cv on Fig. l. Fig. 4 is a side elevation ofthe base ot' the machine with the treadle at tached in its normal position, and Fig. 5 is a plan of the slotted yoke for operating the size-v distributing roll. n

A is the base of the machine, from which rises the standard B, provided with the laterally-projecting arms B' and B4, the rearwardly-projecting ear B2, and the hub B3, in which is formed a bearin g for the shaft O, carrying at'one end the hand wheel or crank D, provided with the hub D', in which is formed the cam-groove Z, as shown.

The base A is provided with the rearwardlyprojecting arm A', to the rear end of which is pivoted the treadle I, connected by the rod H to the rear end of the lever G, pivoted at a to the arm B4, and having set in its front end the screw-bolt F, provided at its upper end with a convex-ended head, upon which rests the shank E' of the carriage E, iitted to and adapted to be moved up and down in a vertical bearing formed in the arm B', as shown.

The carriage E has set in its under side the rod p, which extends downward thereform through the stud q, and is surrounded between its head 1o' and the stud q by the spring o,

which serves to assist the downward movement of the carriage E'when the front end ot' the lever G is moved downward, and the rod p prevents the carriage E from being rotated about the axis ot' its shank.

P is a pivoted frame carrying thesize-cylinder Q, size-roll Q', and the size-distributing roll Q2, the shaft of lwhich latter roll is provided with the slotted yoke B, which engages with the rod j', projecting upward from the ring j, which surrounds the hub D', and is moved to and fro thereon by themam-groove l acting upon the inner end of the screw kset in said ring, said ring being prevented from moving about the axis of the hub D' by the pinm set in the standard A, as shown.

So far, with the exception that the carriage is held from being revolved or moved about the axis of its shank, the machine is constructed precisely like the machine descrlbed in another application of even date herewith, andthe parts thus described, taken'by themselves, form no part of my present invention.

Instead ot' the bed-roll and the stand and centers ior carrying the same described in the application referred to, I use a dat circular bed, L, `provided with a central convex-ended pintle, b, which rests on the bottom of a recess or socket formed in the upper surface of the carriage E, and is surrounded by the rubber tube c, which fills the space between the periphery of said pintle and the vertical walls ot' said socket, and serves to keep the bearing of said pintle central in the socket, while at the same time it permits it to be slightly inclined in either direction to accommodate the upper surface of the bed or table L to slight inequalities in the thickness of the material being acted upon. The upper surface of the bed or table L is covered with a cushion, e, of rubber, drawn tightly over the top of the table in the form of an inverted cup and secured thereon by the ring f. The bed or table L is prevented from being moved about the axis of the pintle b by the pin h, set in the carriage E and entering a hole in the under side of the table L.

M is a hat die secured to the periphery ot'l the cylinder M', mounted upon the shaft C so as to rotate therewith. The under surface of the die M has formed thereon the desired design in relief.

S is a gas-burner, which may be of any com venient form, and serves to heat the die when it is desired to cover the design with metallic leaf.

J is aspiral spring, for maintaining the treadle I in its normal position when the operators foot is removed therefrom.

If it is desired to emboss a single small tigure in wood or other compressible material to be covered with bronze, the screw F is adjusted to raise or lower the tableL till the distance between said table and the under surface of the die M is a little in excess of the thickness of the piece of material to be acted upon, and

4the size-rolls are placed in the position indicated in the drawings, With the cylinder Q in contact with the cylinder M, and size is applied thereto. The operator now rotates the Wheel D to bring the face of the die M into contact with and move it past the periphery of the size-cylinder Q, which deposits upon the relief portions of the design a coating of size. When the die M has again assumed the position shown in the drawings its rotary movement is arrested, and the operator places the material to be acted upon. in the desired position upon the table L, and, placing his foot upon the treadle I, depresses it, thereby raising the table L and thematerial resting thereon until the material is pressed hard against the die and the relief portions of the design are pressed into the material to a sufficient depth, the table L, by virtue of its peculiar bearing-sul'iport, accommodating itself to any inequalities in the thickness of the material.

If it is desired to cover the design with metallic leaf, the frame P is thrown backward to raise the cylinder Q from the-die-cylinder M', and the wheel D and die-cylinder M are allowed to remain in the fixed position shown in the drawings. The piece of material to be ornamented is coated with the appropriate size forthat purpose, and the leaf islaid thereon, when the article isplaced in position on the table L and forced upward against the die M, which has been previously heated by a jet of iiame from the gas-burner S, and the leaf is set wherever thel hea-ted die has applied pressure to it.

I do not claim, broadly, in this application the spring attached to the treadle-lever, the gas-burner for heating the die, the convexended pintle for supporting the table L, or the rubber ring surrounding the same, as all of these devices are shown and described in anv other application ot' even date herewith.

Vhat I claim as new, and desire to secure by Letteis PatentI of the United States, is-

l. The combination of the rotary Shaft C, the dat-sided die-cylinder M Ml mounted thereon, the yflat work-supporting table or bed L, supported by a convex-ended pintle, b, and the size-rolls Q, Q', and Q2, all arranged and adapted to operate substantially as described.

2. The cylinder M', having formed upon or secured to one side thereof the fiat die M, with a design in relief formed thereon, and adapted to be rotated about the axis of the shaft C to receive a coating of size, and to remain in 'a state of rest while receiving the impression, in combination with the dat surfaced table L, suppoited by a convex-ended pintle, b, and mechanism for imparting to said table a vertical movcment, substantially as and for the purposes described.

Executed at Boston, Massachusetts, this` 29th day of April, A. D. 1881.
